White exhaust smoke is usually the result of condensation and moisture buildup in the exhaust system; it can also be the result of burning coolant within the engine. When white exhaust smoke is thin and vaporous, it usually does not signify a problem within the car.Know More
If the exhaust smoke is thicker and comes out in large clouds, it generally means that there is something burning within the car. A blown head gasket could be a possible reason for coolant burning in the car; a cracked engine block is also a reason for coolant burning in the vehicle.

A true dual-exhaust system helps to improve the performance of a V-6 or V-8 engine by splitting the exhaust from the two banks of cylinders. However, it is less effective on smaller vehicles that use an inline four-cylinder engine. The system reduces the pressure to expel the exhaust fumes, allowing the engine to send more energy to the transmission.Full Answer >
